| 英文摘要 | a simple oxygen permeation model was developed based on the theoretical analysis of the role of interfaces of mixed conducting membranes. the developed model equations contain three resistance constants, which can be determined by correlating oxygen permeation flux to oxygen partial pressure on each side. a series of experimental measurements of oxygen fluxes of ba0.5sr0.5co0.8fe0.2o3-d membranes over a wide range of temperature and oxygen partial pressures were tested for the regression of three resistance constants with good correlation (r > 0.997). with this model, the interfacial exchange resistances of each side can be well distinguished from the bulk-diffusion resistance under a wide-temperature range. the kinetics parameters, including interfacial exchange coefficients on each side and ionic diffusion coefficient, can be obtained through the three resistance constants. parametric studies can predict the influences of membrane thickness, oxygen partial pressures on oxygen flux, distribution of permeation resistances, and characteristic thickness.
